As a pioneer in the field of big data transmission synchronization, Raysync has overcome these challenges in a groundbreaking way, achieving secure, reliable, and efficient data migration. Part 1: Industry Needs With the continuous development and growth of global business, chip manufacturers' headquarters often need to regularly collect a large amount of data from production environment clients in various factories for analysis. During the transmission process, there are many transmission problems such as slow transmission, high latency, and packet loss, and it requires the intervention of operation and maintenance personnel in each factory to perform the transmission task, which increases the operation and maintenance time cost of the headquarters to collect data from various factories.  Part 2: The problems faced by the chip industry: ➤ Due to the impact of transmission distance and network conditions, the transmission efficiency of huge data volumes lags behind. ➤ Poor transmission reliability, unable to ensure the accuracy and security of transmitted data. ➤ The existing transmission methods cannot automatically transmit large amounts of data to a specified storage location on a regular basis. ➤ Due to the large number of data files collected by each production plant, the use of TCP protocol file transfer often only utilizes 25%-35% of the storage performance, resulting in a waste of hardware resources. Part 3: Raysync solution Raysync provides transmission solutions between the headquarters of chip manufacturers and their factories, as well as between the centralized storage servers and terminal devices of each factory. Raysync's self-developed transfer protocol helps chip manufacturers to transfer data at high speed between their daily operations and factories around the world.   1. Automation synchronization between headquarters and factories The headquarters machine room deploys the Raysync server system, and each factory deploys the Raysync client to achieve automated high-speed file transfer synchronization between the headquarters and factories. At the same time, the Raysync server is deployed in a clustered manner, and files are synchronized from the centralized storage servers in each factory through multiple concurrent tasks, effectively improving storage performance utilization and avoiding waste of hardware resources. 2. Automation synchronization between factories and terminal devices Each factory deploys a centralized storage server for the Raysync, and a Raysync client for the terminal devices, enabling the automatic collection of data files from various terminal devices in the factory. At the same time, through the Raysync multi-node management function, centralized management by the server is achieved, and the automatic synchronization and uploading of file data from each client are controlled in a unified manner, without the need for manual upload/download by human intervention, without the need to adjust the existing network architecture, and without the need for new network/hardware costs. The Raysync is hundreds of times faster than the original speed Raysync 's UDP optimized transmission technology is an innovative software that eliminates the fundamental shortcomings of traditional file transmission technology based on TCP. It transmits through Raysync's self-developed transfer protocol, which is hundreds of times faster than FTP/HTTP, greatly reducing the time required for user file decompression and significantly improving the efficiency of file upload/download by 75%-85%. At the same time, the headquarters effectively utilizes storage performance through cluster deployment to avoid waste of hardware performance.  Guarantee data integrity Relying on Raysync's transfer mechanisms such as resume from a breakpoint, multiple checks, and automatic error retransmission, it effectively guarantees the reliability of file transfers and ensures the integrity of data across factories. Algorithm encryption secure transfer SSL security features are added to the transmission protocol and data channel, and TLS algorithm encryption is used to achieve AES-256 financial-level encryption strength , protecting the privacy and integrity of data transmission across factories. Reduce human operation, improve efficiency, and reduce personnel costs Raysync has an automatic synchronization function that enables client data from factories around the world to be synchronized with a centralized storage server in real time. The data is then automatically uploaded to the corresponding storage server at headquarters on a regular basis through the centralized storage server, ensuring that headquarters can obtain the latest data in a timely manner.

What is UDP protocol? UDP, User Datagram Protocol, is a connectionless transport layer protocol and part of the TCP/IP protocol suite. UDP is known for its high transfer efficiency and is suitable for data transfer scenarios with high real-time requirements. Let's see what the UDP protocol is in terms of how it works, advantages, use cases, and pros and cons. How does UDP work? UDP is a connectionless protocol, so it does not require establishing a connection like TCP. UDP datagrams do not undergo serialization, packaging, and unpackaging processes like TCP packets, and it does not provide data guarantee mechanisms during data transfer. UDP's main responsibility is to deliver data to the destination endpoint without confirming whether it has been received correctly. Therefore, UDP can be used for fast data transfer with high real-time requirements. The main features of UDP 1. Simple and Fast: As UDP does not require connection establishment and maintenance, data transfer speed is very fast. 2. Small Header Overhead: UDP headers are only 8 bytes compared to TCP's 20 bytes, saving bandwidth. 3. Multicast and Broadcast: UDP supports multicasting and broadcasting, making it more efficient to broadcast to multiple nodes. 4. No Congestion Control: UDP does not provide guarantees for data packet integrity and does not support flow control, congestion control, and similar mechanisms. Therefore, in situations where network quality is less than ideal, UDP transfer may result in data loss or duplication. In summary, UDP is suitable for applications that prioritize fast transfer and real-time requirements over guaranteed delivery and reliability of data. Use cases of UDP 1. Audio and Video Communication: UDP protocol is suitable for real-time audio and video communication applications such as IP telephony and video conferencing. 2. Multiplayer Games: UDP protocol is also suitable for data transfer in multiplayer online gaming, such as Dota 2 and League of Legends. 3. DNS Protocol: Domain Name System uses UDP protocol for domain name resolution, allowing for quick response when multiple clients access the DNS server simultaneously. 4. Broadcasting: UDP protocol is suitable for transmitting data to multiple nodes through broadcasting. Pros: 1. Low Latency: UDP protocol is more suitable for scenarios that require fast data transfer compared to TCP protocol. For example, video conferencing and real-time monitoring applications require minimal data transfer latency to prevent video stuttering and excessive delays. UDP protocol effectively minimizes latency. 2. Support for Broadcasting and Multicasting: UDP protocol supports broadcasting and multicasting, making it widely applicable for data transfer among multiple devices or clients. 3. Low Overhead: UDP protocol has a small header of only 8 bytes and does not require establishing a connection. Therefore, it has minimal overhead during data transfer, leading to more efficient data transfer. 4. Ease of Implementation: Compared to TCP protocol, UDP protocol generates significantly less overhead. As a result, it is easier to implement compared to TCP protocol. Cons: 1. Unreliable: UDP protocol does not provide guaranteed packet integrity and does not support mechanisms such as flow control and congestion control. Therefore, in cases with poor network quality, data transmitted through UDP protocol may be lost or duplicated. 2. Poor Security: UDP protocol lacks encryption and authentication mechanisms, making it vulnerable to attacks by hackers. What is UDP-based data transfer protocol? The Raysync high-speed file transfer protocol is a core technology created by Raysync based on the UDP data transfer protocol. To address the limitations of UDP protocol, Raysync Protocol optimizes upon UDP to enhance the reliability, stability, and overall user experience during data transfer. 1. Congestion Detection and Handling: Raysync Protocol's congestion detection algorithm collects background transfer information along the path. It accurately determines the congestion situation based on the transfer speed, neither overly conservative nor overly aggressive, effectively utilizing path bandwidth. 2. Packet Loss Detection and Recovery Mechanism: Raysync Protocol introduces a new ACK data algorithm that accurately detects packet loss and initiates data retransfer promptly, without relying on cumulative acknowledgments or ACK timeout timers. This greatly improves transfer speed and real-time data transfer. 3. Packet Fragmentation and Reassembly: Raysync Protocol efficiently handles packet fragmentation and reassembly, supporting data stream optimization and protocol conversion. 4. transfer Encryption and Authentication: Raysync Protocol employs bank-level AES-256 encryption and TLS encryption during transfer, supports national cryptographic standards, and implements multiple file verification methods . Additionally, Raysync Protocol utilizes login 2FA authentication and permission settings, ensuring stricter access control. How does Raysync Protocol automatically switch between UDP and TCP in transfer? Raysync Protocol can dynamically and intelligently switch between UDP and TCP protocols based on the network conditions for data transfer. When the network quality is good, Raysync automatically selects TCP protocol for transfer to guarantee data stability and reliability. When the network quality is poor, Raysync automatically switches to UDP protocol to achieve lower latency and higher transfer speed. Through this dynamic and intelligent protocol-switching mechanism, Raysync Protocol can adapt to the actual network conditions, automatically selecting the optimal data transfer method to enhance user experience and data transfer efficiency. Moreover, due to the distinct characteristics of TCP and UDP protocols, Raysync's intelligent switching allows it to adapt to different business scenarios and requirements, improving its flexibility and applicability.

Part 1: What is File Transfer Protocol ? File Transfer Protocol is a set of standard protocols used for file transfer over the network, which works at the seventh layer of the OSI model and the fourth layer of the TCP model, i.e., the application layer. This ensures that the connection between the client and the server is reliable and connection-oriented, providing a reliable guarantee of data transmission. Part 2: How does File Transfer Protocol Work? File Transfer Protocol uses the user interface of the Internet's standard file transfer protocol, FTP, to provide users with a set of applications for managing file transfers between computers. FTP is designed based on the client-server model, where two communications channels are established between the client and the FTP server. Command Channel cannot perform the task of transferring data and can only be used to transfer control information such as internal commands executed by FTP and the responses to the commands; Data 12Channel is a connection for transferring files between the server and the client, which is full-duplex and allows simultaneous data transfer in both directions. This idea of separate transmission of commands and data greatly increases the efficiency of FTP, while other client server applications typically have only one TCP connection. Th121 client initiates a conversation with the server when the user requests the server to download a file. Using FTP, the client can upload, download, delete, move, and rename files on the server. Part 3: Two Modes of FTP FTP client initiates FTP session and establishes corresponding connection with FTP server. Two channels are to be established during FTP session: control information process and data process. Standard : Standard mode FTP client sends PORT command to FTP server. Passive : Passive mode FTP client sends PASV command to FTP Server. Part 4: FTP Transfer Method The task of the FTP is to transfer files from one computer to another, independent of the location of the two computers, the way they are connected, or even whether they use the same operating system. There are two ways to transfer FTP: ASCII, Binary. ASCII Assuming that the file the user is copying contains simple ASCII text, if the remote machine is not running UNIX, when the file is transferred ftp will usually automatically adjust the contents of the file to facilitate the interpretation of the file into the format in which the text file is stored on the other computer. Note: It is often the case that the file the user is transferring contains files that are not text files; they may be programs, databases, word processing files, or compressed files. Before copying any non-text files, use the binary command to tell ftp to copy them. Binary In a binary transfer, the bit sequence of the file is preserved so that the original and the copy are bit-by-bit one-to-one. Even if the file containing the bit sequence on the destination machine is meaningless. Note: If a binary file is transferred in ASCII, it will still be translated even if it is not needed. This can corrupt the data. Part 5: User classification of FTP Real Account This type of user is the one who has an account on the FTP service. When this type of user logs in to the FTP server, their default home directory is the directory named by their account. However, they can also change to other directories. For example, the home directory of the system, etc. Guest User In FTP server, we often set up an account for different departments or a specific user. However, this account has the feature that it can only access its own home directory. In this way, the server secures other files on the FTP service. An account with this type of user can only access the directories under its home directory, but not files outside its home directory. Anonymous User This is also what we usually call anonymous access. This type of user is not assigned an account in the FTP server, but he/she can still access some public resources anonymously. Part 6: The Development of FTP FTP is the oldest network tool in the development of the Internet. From 1971, when the first RFC for FTP was proposed by A KBHUSHAN to nearly half a century ago, FTP has been one of the most important and widely used services in the Internet with its unique advantages. With the continuous development of the Internet, the FTP specification has undergone several revisions to accommodate network standards including TCP/IP. In 1980, jon postel, a scientist at the Institute of Information Science at the University of Southern California, defined a new version of FTP in RFC 765. In 1985, RFC 959 redefined FTP, this time introducing new administrative features, including the ability to create and delete file directories. In 1997, REC 959 was updated to provide new features defined in RFC 2228 to provide security features. In 1999, FTP was updated to RFC 2428 to support the IPv6 protocol. Part 7: 7 Common File Transfer Protocols FTP FTP is a network protocol for transmitting files between computers over Transmission Control Protocol/Internet Protocol connections. Within the TCP/IP suite, FTP is considered an application layer protocol. FTPS FTPS a multi-transfer protocol, equivalent to an encrypted version of FTP. When sending and receiving files on the FTP server, you face two risks. The first risk is to encrypt the files when uploading files. The second risk is that these files will stay on the FTP server while waiting for the recipient to download them, at which point they need to be secured. Measure: Choose to create an FTP server that supports SSL, i.e., use an encrypted control and data channel with an SSL layer under the FTP protocol to allow the host to upload these files using an FTPS connection. TLS & SSL TLS is an industry standard designed to protect the privacy of information during network communications, allowing client and server applications to detect security risks including message tampering, message interception, message forgery, and its predecessor, SSL. TLS and SSL encrypt network connections at the transport layer, but work below the application layer. SSL security extensions have at least two different initialization methods: explicit security and implicit security. SSH(Secure Shell） SSH is a security protocol based on the application layer. SSH is currently a more reliable protocol that provides security for remote login sessions and other network services, and the use of SSH protocol can effectively prevent the leakage of information during remote management. SCP The SCP protocol is an application layer protocol that defines the process of transferring files "between local and remote machines" or "between remote and remote machines". The SCP protocol is based on the SSH protocol, so file transfers based on the SCP protocol are secure. SFTP SFTP is a secure file transfer protocol that provides a secure encryption method for transferring files. It has almost the same syntax and functions as FTP, but SFTP is part of SSH, a secure way to transfer files to a server. SFTP also uses encryption to transmit authentication information and the transmitted data, so it is very secure to use SFTP. However, because this transfer method uses encryption/decryption technology, the transfer efficiency is much lower than normal FTP. If you require higher network security, you can use SFTP instead of FTP. HTTP & HTTPS HTTP is the basis for data communication. It defines the message format for communication between a Web browser and a Web server, and how the Web browser should respond to Web requests. HTTP uses TCP as the underlying transport and is a stateless protocol. This means that each command is executed independently and the receiver does not retain session information. Https is a secure version of HTTP in which communication is encrypted via TLS or SSL.

There are many kinds of enterprise documents, and the irregular operation of employees leads to the leakage of enterprise core documents from time to time. How to ensure the safety of document delivery? Raysync has released a new function in version 5.0.7.8 - high-speed file sharing download link binds to the first device, which makes administrator manage the file sharing conviencetly. 1. Function Introduction Check th option "Bind the first device when open the share link to download" in Raysync admin console. When this function is turned on, after the employee shares the file with the his partner through the "Share Download" link, only the first device is allowed to open and download, and this device will be recorded in the background. If you want to share it with multiple people, you need to notify the administrator and perform Unbind before the new device can reopen the link. For some enterprises with strict file security control, this function can well realize visual, controllable and traceable file outgoing, effectively control file outgoing and prevent data leakage. 2. Settings Step 1: Log in to the admin console. Step 2: Enter the admin console, check "Bind the first device when open the share link to download" in Settings-> General-> Common Settings. *The system is disabled by default and needs to be manually enabled by the administrator according to actual needs. 3. User Opeariong Interface The first device can open the downloadn link, view and download the file normally. If the other device try to open this link, the error prompt "This device is not authorized" will pop up. 4. Sharing Management The administrator can check the user who created the shared link, link share time, expired time, whether bind to the first device or not, and the device ID that binds as the first device. Besides, the administrator can also cancel and delete the file, unbind the link from the first device. After unbinding, you can reopen the link on a new device. As a one-stop file big data transfer solution expert, Raysync has a self-developed Raysync ultra-high-speed transmission protocol, which can easily meet the fast transmission requirements of TB-level large files and massive small files, and has provided high-performance, stable and safe data transmission services for 2W+ enterprises in IT, finance, film and television, biological genes, manufacturing and many other fields.

Today's data-driven world is demanding, requiring accuracy, speed, integrity, and most importantly safety. This is a daunting task. In the past, many organizations have relied heavily on the old version of the file transfer protocol to transfer files. But over time, FTP alternatives have become necessary because the security of this method has been tested by hackers. 4 Alternatives to File Transfer Protocols FTP alternatives include SFTP, HTTPS, AS2, and MFT. For example, in 2001, a serious breach occurred at Yale University, when more than 43,000 user IDs were exposed and all data was carefully collected from the FTP server. In the same year, Acer's customer details were stolen similarly. Moreover, credentials for 7,000 FTP sites have been distributed in underground forums, including the FTP server run by The New York Times. Security and file transfer are important issues for IT security professionals, but what is the best way to protect company data? Take advantage of more secure options. As many organizations gradually move beyond traditional FTP, they have chosen modern and secure FTP alternatives to transfer data, including: 1.SFTP_ SFTP is also known as FTP over SSH. It uses a secure channel between computer systems to prevent unauthorized disclosure during the transaction process, thereby reducing the risk in the data exchange process. The authentication of the SFTP connection involves user ID and password, SSH key, or both. It is also firewall-friendly and only needs to open a port number. 2.HTTPS Many sites tend to use HTTPS instead of traditional HTTP, but what are the main differences? First of all, traditional HTTP does not encrypt browser traffic, which brings security risks. In contrast, HTTPS uses Transport Layer Security to provide an additional layer of encryption. This will create a secure channel, so the integrity of the data will not be changed without your knowledge. HTTPS is very suitable for file transfer, where trading partners need a simple browser-based interface to upload data. 3.AS2 This is a popular method to safely and reliably transmit EDI data over the Internet. AS2 generates an "envelope" for data, allowing it to be sent using digital certificates and encryption. For example, Wal-Mart is widely known for its use of EDI through AS2 and has played an important role in driving adoption in the retail industry. 4.MFT The way to support the above options and make FTP more secure is Managed File Transfer . This security option simplifies the data exchange between the system, employees, and customers. It supports multiple protocols and encryption standards, and MFT provides a wide range of security functions that can meet strict security policies to comply with PCI DSS, HIPAA, GLBA, and other regulatory requirements. The MFT solution provides advanced authentication and data encryption to provide safe and reliable file transfer. You can also track user visits and transfer activities through the reporting function. More importantly, managed file transfer can solve other problems or troubles you may encounter, including the need for automatic file encryption, workflow and project automation, file transfer monitoring and notification, and easy file sharing with third-party suppliers and trading partners. In general, managed file transfer provides the best choice. It is a secure FTP alternative to quickly and effectively manage data transfers through detailed audit records. It is preventive, not reactive, which is most needed by security experts in today's environment. It is supported on many platforms , cloud , and hybrid environments), so you can safely transfer files anytime, anywhere.

The file transfer protocolserver runs a program that utilizes the file transfer protocol and allows you to upload and download files. By default, the file transfer protocol is not secure because the data it transmits is not encrypted. All file transfer protocol servers on this list include options for encrypting and protecting data by using secure protocols such as SFTP or FTP/FTPS. File transfer protocol servers are usually used to allow remote workers to upload or download files from the server. Network and system administrators also use it to back up network configuration and run updates. There are many file transfer protocol server programs available, from free software with basic functions to commercial products with advanced functions such as mobile device access. In this article, I will share the best file transfer protocol server for Windows. 1. FileZilla Server FileZilla is an open-source FTP server for Windows. It supports FTP and FTP over TLS, the latter can provide encryption between the server and the client. FileZilla server has a simple and easy-to-use interface. It provides the basic functions expected in an FTP server, such as creating user accounts, speed limits, logging, IP filtering, groups, and fine-grained permissions. For basic FTP tasks , this is a good choice. It lacks corporate functions, so I will be cautious when providing it to the outside world. It uses FTP by default, so it is not secure and you will need to enable FTP over TLS to encrypt traffic. The setup is easy, just run the installer, select a management port and start the server interface. Then, you only need to create a user or group with permissions to the home directory to start using it. 2.SolarWinds SFTP/SCP Server SolarWinds SFTP/SCP server is designed for network and system administrators. It is an ideal FTP server for backing up configuration files, downloading images, and transferring large files. By default, it is secure and uses TCP port 22 to safely transmit data over an insecure connection. I use it to back up the configuration on Cisco routers and switches. Installation is very simple, with minimal configuration , and you are ready to go. It can be set to run as a service, so it is always available. 3.Serv-U Serv-U is designed for small businesses that need to transfer files quickly, easily, and securely. Serv-U supports FTP and FTPS for secure file transfer. You can use SSL or TLS to encrypt communications to protect data during transfer. One of my favorite features of this product is the ability to transfer files from a web browser or mobile device. This eliminates the need for users to set up an FTP client to download or upload files. The web and mobile interface makes it easy for you to view, upload and download files. Using interactive drag and drop options, your users can share files from anywhere. Other features include support for large file transfers, monitoring sessions, and fine-grained control of bandwidth, storage, permissions, and access.
